we (heart) gregorio [aka a public service message]brighten, ditto on the
yah, me either, but i've missed gregorio's entertaining posts sooooooooooo much. and let's not forget his charming way with insulting and attacking anyone who dares question his (self-proclaimed) authority. thread after thread where he rants about the evil of hi-res and seemingly tries to perform total revisionism of digital audio theory, he disappears after being called out by people who actually understand digital signal processing, data conversion, systems theory and implementation etc.
it was heartbreakingly difficult going through gregorio withdrawl last year when he disappeared late-June, away from HF for almost 8 long months, after having been exposed as not even understanding digital audio basics: sampling theory, quantization, etc.....
"G" had for months ignored or responded dismissively to PMs and posts from numerous folk attempting to help with his misconceptions..... whenever challenged or questioned, avoiding or deflecting, spitting back defensively -- the standard response (when there was any technical reference) usually mentioning "dithering quantizers" or, more often, his extensive experience working with (insert big orchestra, or conductor, or artist name here), of having been involved with audio since people were in diapers or somesuch, of owning incredibly glorious equipment.... and inevitably when challenged, structuring his response in a fashion always including himself in the referenced group (note gregorio's heavy use of the royal "we" when quoting tasty snippets of digital audio theory, or namedropping, often using info out of context)...
saying he's going to leave head-fi and go post somewhere else where he is appreciated.....and finally admitted he doesn't understand the mathematics or technology underlying digital audio.
then of course there was the theme of presenting himself as a (university) "lecturer" but it turned out he is a pro-tools instructor.... not surprising, as much digital audio posting pretty much read like pro tools documentation boilerplate.
reappeared in Feb 2009, seems to have read a few well-referenced (but in some cases controversial) websites/books/papers: came back with a vengence, regurgitating those sources (and dropping names extensively) and emotionally -- and often derisively -- presenting their content as fact rather than the experimental, marketing, or opinion pieces that they in some cases were. however, even in his very entertaining personal digital audio manifesto thread (http://www.head-fi.org/forums/f133/2...ploded-415361/ ) still misses some basic understanding about sampling theory and quantization
doesn't look like his stance has changed much, wrt hi-res or much else.
but lo! just when we've missed gregorio's attempts to redefine digital, fully revise many decades of communications theory, sampled-data systems, data conversion technology and the like; he takes on linear systems!
there's a great thread also in Sound Science where he attempts to redefine how gain is calculated (ie how amplification works); not surprisingly, when he was called out on this one and asked to explain, he simply disappeared again (to quote another head-fier: "I'm curious about the answer as well – but I doubt it will be clearer than what we got so far if it arrives at all." http://www.head-fi.org/forums/f133/w...ml#post5702792)
for a person who goes to such lengths to tell the HF community how experienced and important he is in recording, mastering, production.... it's odd.... these little basic underlying freshman mistakes.... and gregorio invests lots of time posting extensively on Head-Fi; but there don't seem to be posters with a similar style or profile on any of the major recording, mastering or pro audio equipment webboards.....
if you'd like to have your own entertainment to see what you've missed (or just verify and expand upon the few charming concepts noted above), grab a tasty burger or your favorite beverage, sit down and go back through gregorio's post history (2008 up through when he disappeared end-June, and then onward from the glorious return in 2009 february).
makes for reading about hi-res....
btw, me? I happen to believe that well-mastered sessions presented in hi-res -- whether SACD or extended-resolution PCM -- through well-designed hi-res DACs and playback electronics, often present a significant improvement in sound over redbook.
for some interesting apples-to-apples comparison using files of varying bit depth and sampling frequencies, sourced from the identical master, check out some of the new 2L products, or mastering engineer Kent Poon's "Audiophile Jazz Prologue III" (aka AJP3) demonstration product available through his site Design w Sound
now where's the salt....
